James Wilson contributed to the JBoss World of MBeans a simple but very useful service for monitoring mbean attributes and logging the results to files. After being on the JBoss wiki for a couple of months with people already using it, I finally got the time to integrate it with the JBoss codebase so it becomes part of the next jboss release, i.e. JBoss v4.0.3.

You can read about this nifty little service here.
